Bacterial study
In all treatments, Lactobacillus bacteria successfully colonized
both the larval digestive tract and the culture sea water (Table 1).
Total bacterial counts among probiotic probiotic-supplemented
groups were significantly different from total bacterial counts in
controls in water and digestive tract of larvae (pb0.05). The mean of
total bacterial counts in control' water was approximately 4×104-
fold increased exponentially from the experimental groups in water
(pb0.05). The opposite pattern was observed for the digestive
tracts of larvae in which the mean of total bacterial counts among
probiotics administered groups were was more than control
(pb0.05). However, the flora in probiotic treatmentswas significantly
different from the flora in control (pN0.05). On the other hand, Lactobacillus
colonization was detected artificially dominant in experimental
groups, however, no colonization was observed in both thetank's water and the digestive tract of S. aurata larvae in control
group
